Impacts of Voids, Line of Sight Interactions, and Local Emission Environment on Detectability of Gamma-Ray AGN
Ollie Jackson, Amy Furniss, Olivier Hervet +2
Cosmic voids may have novel affects on the propagation of high-energy photons. We consider the fraction of the line of sight that intersect voids (termed \enquote{voidiness}). A pr…
Exploring Invisible New Physics with Exotic Pion Decays
Wolfgang Altmannshofer, Jeff A. Dror, Pierce Giffin +5
We study the sensitivity of past and future stopped-pion experiments to light, invisible dark sector particles produced in exotic pion decays. We consider two-body decays involving…
A Study on the Line of Sight to Galaxies Detected at Gamma-ray Energies
Amy Furniss, Josepf N. Amador, Olivier Hervet +2
The large-scale Universal structure comprises strands of dark matter and galaxies with large under-dense volumes known as voids. We measure the fraction of the line of sight that i…
SHIMM as an atmospheric profiler on the Nickel Telescope
Ollie Jackson, Maaike A. M. van Kooten, Saavidra Perera +2
Optimal atmospheric conditions are beneficial for detecting exoplanets via high contrast imaging (HCI), as speckles from adaptive optics' (AO's) residuals can make it difficult to…
